Implementation of modern meteorological models for improving the performance of solar power stations

Implementation of modern meteorological models for improving the performance of solar power stations

Weather and climate conditions are some of the primary factors influencing the performance of renewable energy power plants, particularly the performance of photocells in solar batteries.

Weather factors.

Obviously, the intensity of solar radiation has the greatest effect. The efficiency of solar panels is reduced if solar radiation intensity is reduced or absent altogether.

Temperature
Solar batteries perform better at lower temperatures than in a hot climate. Electrical output may be more than normally efficient in winter, in temperatures below freezing.

Cloud cover
Solar radiation reaching the earth’s surface decreases as cloud cover increases. Solar batteries receive maximum sunlight on cloudless days with direct rays of the sun. These are the peak hours when they will be producing the most energy. The light received decreases as the cloud cover increases. Solar batteries will produce minimum usable energy on heavily overcast days. The batteries will work at half their efficiency when there is enough light for objects on the ground to cast a shadow.

Climatic conditions and topography.

To a considerable extent, climatic conditions depend on topography.Mountains, seas and oceans, large lakes and their location relative to each other exercise the greatest influence on the formation and behavior of clouds and on the temperature.This results in the amount of solar radiation in adjacent regions with different topographies varying radically. For example, mountains may get less solar radiation than neighboring foothills and plains. The amount of solar radiation in coastal areas may differ from inland figures.

All these factors need to be taken into consideration in designing plant infrastructure for planning electrical consumption and load.This makes the accuracy, and hence the source, of weather data very important.

Relevance of data is not guaranteed by proximity to a meteorological station in regions with complex topography, such as in mountainous areas or simply areas with sharp changes in elevation.
At present, complex weather calculation models, which it has become possible to generate using modern technologies such as IoT, Cloud Services, and Big Data, are used to obtain accurate weather data.

OpenWeatherMap weather service is based on the VANE Geospatial Data Science platform for collecting, processing, and distributing information about our planet through easy to use tools and APIs.
We are collecting data from weather stations and forecasts of meteorological services and research laboratories, combining long-term and short-term forecasts with real-time data from weather stations, processing them and immediately updating current weather and forecasts in our API. Today we have more than 40,000 weather stations.
Data is stored in the VANE database and processing with our unique algorithms to create interpolated data of current weather conditions anywhere in the world, as well as into a variety of weather maps.

How weather indexes affect road traffic strategy

How weather indexes affect road traffic strategy

One of the strongest reasons to check the weather forecast is road traffic safety. Unfortunately, any weather change leads to an increasing number of road traffic crashes. However contrary to popular belief, one of the main reasons behind traffic collisions is neither sudden snow fall nor unexpected rain, but driver’s lack of knowledge about the weather influence on road traffic safety on the whole. And consequently, a significant part of drivers do not pay proper attention to a current weather forecast and they choose an inappropriate for the present weather way of driving. For example, many drivers comply with road speed limits only when the weather is really nasty, and such measures as usage of fog lights and reduction of cases when a driver changes a lane are rarely used. Nevertheless, even a light rain or haze can lead to increasing braking distance of a vehicle and trigger an accident.  

And what is particularly bad, the aggravating weather conditions enlarge an amount of cases when pedestrians are involved in traffic collisions. A driver does not plan to be a killer, but sadly such accidents happen often nowadays. Statistics say that in town areas every tenth crash is a collision of a vehicle with pedestrian.

Travel countdown, weather, tours and inspiration

Travel countdown, weather, tours and inspiration

With Ready Set Holiday application and weather data by OpenWeatherMap you can perfectly plan your weekend holidays. 

Everyone travels not like others. 

One is suddenly struck by an idea, he grabs a backpack, some clothes, gadgets, buys a ticket  not of great importance where or  gets a bike or a car and sets out for adventures despite a burning sun or heavy rain outside. 

However the most people prefer to plan their trips thoroughly in advance. And often this planning brings as much pleasure as the trip itself.
One wishes that everything in a trip is greatly planned and goes smoothly. Actually it’s a nice occupation to learn an area by map and photos, to check forecasts for all the future locations, to choose and book tours scrupulously considering the experience of former travelers. And weather here is a quite crucial factor. A trip which is planned without regard to forecast has a risk not to be ruined completely, but it can frustrate you. Choosing holiday time with attention to forecasts from OpenWeatherMap, you avoid disappointment. Application Ready Set Holiday turns trip preparation to an easy and interesting thing. And our forecasts and current weather let get maximum pleasure from a trip and prevent a bad cold and overheating.        

Pilots are eager to fly. How weather data help to find an airway

Pilots are eager to fly. How weather data help to find an airway

Let's consider one of the new interesting cases where weather data by OpenWeatherMap is used. 

Usually it's not a quick and easy deal for pilots to find an air corridor with appropriate weather for flying. Sometimes a search for a starting point of a flight and for its destination point takes up to 1-2 hours. ParaglidingStart.info is an application which uses real-time weather data by OpenWeatherMap alongside with information from many other sources. The application shows the current weather for possible starting points of a flight. There also can be found forecasts and other information like the description of the areas or the airspaces. One can implement further features for the pilots in the future.

Pilots are eager to fly, not to spend time looking for airspaces appropriate for flying. And OpenWeatherMap team is happy that our data help them to do so.

Smart home. The relation of temperatures "inside" and "outside".

Smart home. The relation of temperatures "inside" and "outside".

From the first glance, ideal temperature is a subjective notion. It's a usual thing when some people open windows widely, while others wrap up themselves in sweaters and drink hot tea at one and the same room.
One badly tolerates heat, another is afraid of cold. When you are in a room, your comfort temperature depends not only on your physical peculiarities as of a human being, but also your comfort temperature is unique for every surroundings you are in.
The quality of isolation, the tasks you do at home, the amount of working equipment - there is a lot of factors which affect our perception of desired temperature. The comfort temperature is a balance between a wish to wrap up yourself in tons of clothes and a rush every 10 min to cold shower.

Intellectual management of buildings. Weather API

Intellectual management of buildings. Weather API

Intellectual management of buildings simultaneously solves 2 crucial tasks: it lets decrease  electric power cost and reduce CO2 emission and it all together has a positive effect on ecology.  
For the present moment there exist ready solutions which allow reasonable management of all the equipment: lighting, air conditioning, ventilation, heating, cooling, secure systems, etc.
Effective tools of monitoring observe functioning of a building in real-time mode: the tools calculate energy consumption, analyze current technical issues, trace surplus of CO2 and its emission.
The analysis of data received with the monitoring tools also implements management of processes taking place in buildings remotely. For getting actual information, one needs only to launch a browser.     

And here an easy access to a huge storage of data arrays is really necessary: data of different kinds comes constantly and is being processed in real-time mode. 
Our OpenWeatherMap team is happy to know that our development of weather APIs which are used as a part of global solutions in such projects throughout the world contributes to increasing of energy effectiveness and thus helps to improve ecological situation.
